将网民分为无知者、传谣者和智者三类,建立了一类具有标准发生率的谣言模型,应用动力学理论和方法研究了谣言模型稳定性分析,并借助计算机数值模拟讨论了如何通过控制参数以达到控制谣言传播的策略.结果表明,只有当“智者”的公信力比较高,广大网民在智者的影响下对谣言具有辨识能力,且不信谣、不传谣,最终将使谣言销声匿迹,传谣者移出系统.这将为管理者制定舆论控制决策提供科学依据. 相似文献

Bordered linear systems arise from many industrial applications, such as reservoir simulation and structural engineering. Traditional ILU preconditioners which throw away the additional equations are often too crude for these systems. We describe a practical implementation of ILU preconditioners which are more accurate and more robust. The emphasis of this paper is on implementation rather than on theory. 相似文献
